RSP and RP Port Connection Guidelines
RSP and RP Port Connection Guidelines
This section contains detailed cabling and signal information for interface and port connections to the
Route System Processor (RSP) or Route Processor (RP) cards. It also provides information for Ethernet
routing and equipment.
Note The generic term RSP card refers to the RSP-440, RSP-440 Lite, and RSP-880 cards, unless otherwise
specified.
Caution Ports labeled Ethernet, SYNC, CONSOLE, and AUX are safety extra-low voltage (SELV) circuits. SELV
circuits should only be connected to other SELV circuits.

Console Port and Auxiliary Port Connection Guidelines

Each RSP/RP car d has two EIA/TIA-232 (formerly RS232) se rial RJ-45 conn ection ports:
•Console port—RJ-45 interface for connecting a data terminal device to the router, which you need
to perform the initial configuration of the router.
•Auxiliary port—RJ-45 interface for connecting a modem.
Note The console and auxiliary ports are asynchronous serial ports. Ensure that devices connected to
these ports are capable of asynchronous transmission.
For the console and auxiliary port locations, see Route Processor Overview, page4-19.
